GUN -SIGHT.

Application led January 9,

T0 all whom t may concern:

Be it known that I, CHARLES H. BARNES, of Ilion, in the county ofHerkimer and State of New York, have invented a certain new and usefulGun-Sight, of which the following is a specification.

This invention has for its object the production of a gun sight andespecially a sight of the class known as peep or rear aperture sights,which is particularly simple and economical in construction and highlyefficient in use; and the invention consists in the combinations andconstructions hereinafter set forth and claimed.

In describing this invention reference is had to the accompanyingdrawings in which like characters designate corresponding parts in allthe views.

Figure l is a side elevation of my gun sight. Fig. 2 is a rear elevationthereof. Figs. 3 and 4 are longitudinal sectional views on line A-A, andB-B Figs. 1 and 2, respectively. Fig. 5 is a fragmentary viewillustrating the parts shown at the 7 lower end of Fig. 3, andespecially the action of the detent and its spring during pivotalmovement of the sight. Figs. 6, 6A, 6B are detail views of the detent.Figs. 7 and 7A are, respectively, a plan and a side elevation of thesleeve. Fig. 8 is a side elevation of the body member.

1 is the base which is shaped to be secured to the receiver of the gun,the same being adapted to be secured in position by screws 2. In theillustrated form of my invention, the base is formed with a pair ofupwardly extending lugs 3 and with a concaveunder surface 4'designed totit upon the upper face of the receiver of the gun.

5 is the body or hinge member or piece extending between the lugs 3 andhinged thereto, the body member having a cylindrical portion formed witha radially extending boss 6 on one side thereof. Said member 5 is alsoformed with a socket 7 extending radially thereinto across the axisthereof, the socket opening through the boss 6 and being arrangedcoaxially therewith.

8 is a hinge pin or screw extending transversely through the lugs 3 andhinge or bodyT member 5 and the socket 7 therein, and tending to clampthe lugs on the sides of the body member 5.

9 is a sleeve extending into the socket 7 of the body member 5 andhaving a trans- Speciication of Letters Patent.

1913. Serial No. 740,991.

yerse opening l0 therethrough for receivlng the hinge pin 8, the sleeveextending above the body member and being formed with an annularshoulder 11 preferably located at its upper end, and with a lengthwiseslot 12.

13 is a sight member having a head at its upper end formed with thesight aperture 14. The member 13 also comprises a stem 15 fitting withinthe sleeve 9 and having a lengthwise tongue 16, Fig. 4, having threadsat its outer end or edge.

17 is a nut encircling the sleeve and having its threads arranged toengage the threads of the tongue 16, the nut being held from endwisemovement, it engaging at its upper` end with the shoulder 11 of thesleeve and being held against said shoulder by a spring18 which takes upany looseness in the threads. Hence accuracy in the adjustment of thesight member 13 is insured. As shown the spring 18 consists of a springwasher encircling the sleeve and interposed between the lower end of thenut 17 and the upper or outer end of the boss 6 of the body member 5.The sleeve 9 is held from turning with the nut by the hinge pin andhence proper relation between the aperture 14 and the base is preservedso that said aperture will always coincide with the aiming alinement.Obviously during the turning of the nut, the sight member 13 will beraised or lowered. If desired, to enable the sight to be readilyadjusted for different ranges of shooting, the nut may be formed with ascale 19 at its upper end, Figs. 1 and 2, coacting with a fixed point onthe collar, the graduations of the scale corresponding to sub-divisionsof the thread of the nut so that the height to which the sight memberwill be raised upon the turning of the nut in the proper direction, canbe determined by the scale. This nut with its scale forms practicallymicrometer adjustment. The nut is also formed with a corrugatedperiphery as shown at 20.

When the rifle is not in use, the peep sight is swung on its pivot untilit lies alongside the contiguous portion of the gun and when in use itis swung into an upright position.

The movable part of my gun sight is held in its upright position bymeans of a spring pressed detent 21 movable through a guide opening 22in one of the lugs 3 and having los a tooth 23 coacting with a notch 24formed 11o in one side Jface of the body member 5, Fig. 8, which comesinto registration with said detent when the body member and partscarried thereby reach the upright position, the tooth 23 and notch 24being so shaped, that is, having complemental inclined sides, that thetooth will/ratchet out of the notch, Fig. 5. The detent is here shown asa cylindrical plunger having its tooth 23, Fig. 6, extendingdiametrically at one end thereof for coacting with the notch 24, thedetent also having an eccentric pin 25 at its other end and also arounding surface 26 above the eccentric pin. This detent is pressed intooperative position by means of a sheet metal spring 27 bearing at oneend at 28 against the outer side face of one of the lugs 3 and at itsother end against the outer face of the plunger, it being provided witha perforation for receiving the eccentric pin 25.

The intermediate part of the spring is formed with an elongated slotthrough which the hinge pin 8 extends and the spring is held undertension by the head 29 of the hinge pin. In order to prevent unduetensioning of the spring, said pin 8 is alsoormed with a shoulder 30contiguous to the head 29, the shoulder being arranged to engage theouter face of one lug 3 and thus ylimit inward movement of the hingepin.

This gun sight is particularly advantageous in that it is particularlysimple in construction, economical in manufacture, highly efficient,accurate and durable in use.
